Alright, I've got it working, and I replaced pit's sounds with Goku's. I also added my favorite DBZ music to FD.

My only other question is, How do you replace the Character Selection Portraits, and the Kirby Hat animations?

So I saw this AMAZING mod of Goku in SSBB.
The link is over here: http://forums.kc-mm.com/Gallery/BrawlView.php?Number=209833

I have no idea where to start when installing it. (What folders do I put it in, where to extract, etc)

I already have the Homebrew Channel and Riivolution installed on my Wii, as I am a NSMBW modder.

You can find a screenshot of my SD Card's file listing here: http://prntscr.com/8qhiu0

Thanks!
